Do you have any tips for my flight to Imperial?
Depending on where you're coming from, your journey to Imperial could be completely stress-free or it could go on forever. We've pulled together some handy tips that will help you start your next big adventure on the right foot. What to pack in your hand luggage:
  • First things first, put in your passport, important documents, wallet and medications. Next, you'll need some in-flight entertainment to while away the hours. A thrilling novel and a laptop crammed with your favourite shows are some terrific options. If you hope to take a short nap, a neck pillow and some earplugs will also be useful. Finally, find room for a few toiletry items so you'll step off the plane looking fresh and ready to go.
Do not pack the following items in your hand luggage:
  • Double-check that you don't have a pocket knife lurking in one of the zippers of your hand luggage. Other banned items include flammable or explosive products, such as aerosol cans and fuel, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Your main priority is to be as comfortable as you can. Opt for shoes that are easy to pull on and off, dress in loose, natural-fibre clothing and remember to bring a sweater in case it gets chilly in the cabin.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of sitting. To reduce your risk on board, drink plenty of water, consider wearing compression tights or socks and keep your legs and feet moving.
How to get through airport security fast when flying to Imperial?
The trick is to be well organised before you get to the airport security gate. That way, you'll be boarding that plane to Imperial in no time at all. Follow these tips and get your holiday off to a spectacular start:
  • First things first. Your ID and travel documents will need to be shown to security personnel. Have them easily accessible so you don't hold up the line.
  • Next up, both you and your hand luggage must be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items like your belt, coat and headphones will be required to go through the machine.
  • All your electronic gadgets, including your laptop and phone, will also need to be separately scanned.
  • Any liquids or gels, such as shampoo or hairspray, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
  • There's a good chance you'll be required to remove your shoes for scanning, so wearing lightweight sneakers is always a smart idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked baggage. They won't be allowed in the cabin.
